Answer:
not enough information
Step-by-step explanation:
The interior angles of any triangle always sum to 180°.
In the triangle, angles C and D are labeled congruent, so the missing angle has measure
180° - 2 (6x - 5)°
This angle is supplementary to the one labeled (11x + 1)°, which means
180° = (11x + 1)° + (180° - 2 (6x - 5)°)
Solve for x :
180° = (11x + 1)° + 180° - 2 (6x - 5)°
0 = (11x + 1)° - 2 (6x - 5)°
0 = (11x)° + 1° - (12x)° + 10°
(12x - 11x)° = 1° + 10°
x° = 11°
x = 11
I am fairly certain it is C
Answer:
0.6
Step-by-step explanation:
The interior angel for this parallelogram is 360° because
180°(n-2) where n represent the total side.
Angle 1+ Angle 3=70°
360°-70°=290°
290°÷2=145°. As a result, the measurements of D2 is D. Hope it help!
